MetaContext

The <structname>GdaMetaContext</structname> represents a meta data modification context: the <emphasis>how</emphasis> when used with gda.meta_store.MetaStore.modifyWithContext, and the <emphasis>what</emphasis> when used with gda.connection.Connection.updateMetaStore.

To create a new #GdaMetaContext use #gda_meta_context_new.

To add a new column/value pair use #gda_meta_context_add_column.

To free a #GdaMetaContext, created by #gda_meta_context_new, use #gda_attributes_manager_free.

Since 5.2, you must consider this struct as opaque. Any access to its internal must use public API. Don't try to use #gda_meta_context_free on a struct that was created manually.

Functions

_cPtr void* _cPtr(Flag!"Dup" dup)
copy gda.meta_context.MetaContext copy(): Copy constructor.
getTable string getTable(): Get table's name to used in the context.
self MetaContext self(): Returns this, for use in with statements.
setColumn void setColumn(string column, gobject.value.Value value, gda.connection.Connection cnc): Sets a new column/value pair to the given context ctx. Column, must be a column in the given table's name setted by #gda_meta_context_set_table () (a table in the <link linkend="information_schema">database schema</link>). If the given column already exists it's value is overwrited.
setTable void setTable(string table): Set table's name to use in the context. The table is one of <link linkend="information_schema">database schema</link> used to store meta information about the database. Use "_tables" to update meta information about database's tables.
